[0023] Hereafter the invention will be described in detail by the preferred embodiment in conjunction with the drawings.

[0024] Referring to FIG. 2, the multifunctional shoes for walking and skating with single roller according to the invention mainly comprise a pulley assembly 1 and a shoe body 2 wherein the pulley assembly 1 is fitted with the shoe body 2 and walking as well as skating are performed by variation of the relative positions between the pulley and the shoe body.

[0025] As shown in FIG. 1 and FIG. 3, the pulley assembly 1 comprises a bracket 11, a roller 12, a shaft 13, rods 14, springs 15, a pushing rod assembly 16, and fastening bolts 17 or the live. The shaft 13 passing through the center of the roller causes the roller 12 to be fixed to the middle of the bracket 11 on top of which rods 14 and springs 15 are provided. Also the pushing rod assembly 16 is secured to the bracket 11 by the nuts 167.

[0026] The bracket 11 has

shape, and at its left and ligate sides the elongated through slots 111 coaxial with each other are provided. Threaded holes 112 and holes 113 for the displacement of the rod perpendicular to the slots 111 and passing through their upper arcuate surface are provided on the top of the bracket 11. Threaded holes 114 for connection the pushing and its sliding holes 115 pass through the front and rear sides of the bracket 11.

[0027] The roller 12 made of elastic material is fitted in the middle of the bracket 11, and has a bearing hole 122 in which the single direction ball bearing 121 is received.

[0028] The single direction ball bearing 121 is pressed into the bearing hole 122, then the shaft 13 is passed successively through the elongated slot 111 on one side of the bracket 11, the single direction beating 121 and the elongated slot 111 on other side of the bracket 11. The shaft 13 together with the roller 12 can move perpendicularly upward and downward in the slots 111 varying the relative highness between the roller 12 and the bracket 11.

[0029] The cylindrical shaft 13 has a boss 131 provided at each of its both ends in the same direction facing downward, and passes through the elongated slots 111 of the bracket 11 as wells as the bearing 121 received in the roller 12.

[0030] Rods 14 are inserted into the sliding holes of the rods 113 on the top of the bracket 11 with the springs 15 which are placed on the upper bosses as of the rods 14 inserted in the holes 113 respectively.

[0031] The pushing rod assembly 16 consists of a pushing rod head 161, a rear connecting plate 162, spring 163, pushing rod connecting bolts 164, pushing rods 165, a front connecting plate 166 and the fastening nuts 167 with the pushing rod connecting bolts 164 and the pushing rods 165 welded with the front connecting plate 166.

[0032] The pushing rod connecting bolts 164 welded to the front connecting plate 166 are inserted into the holes 114 on the bracket 11 passing through the center of the springs 163, while the pushing rods 165 welded to the front connecting plate 166 are inserted into the sliding holes of the pushing rods 115. Also the pushing rod connecting bolts 164 are inserted into holes 1621 in the rear connecting plate 162 and are secured by the fastening nuts 167.

[0034] In the case of skating, the pushing rod head 161 is pressed by force applied from outside, so the rear connecting plate 162 and the connecting bolts of the pushing rods 164 secured to it are caused to move foreward. Meanwhile, the front connecting plate 166 welded to the connecting bolts of the pushing rods 164 and the pushing rods 165 welded to the front connecting plate 166 move foreward along the sliding holes of the pushing rods 115 on the bracket 11 in horizontal direction. When the pushing rods 165 move foreward apart from the elongated slots 111 of the bracket 11, the shaft 13 together with the roller 12 fixed at it move downward extending out from the recess 22 of the sole of the shoe body 2 due to the effect of the springs 15. At this time releasing the force applied to the pushing rod head 161, the spring 163 will press the pushing rod assembly 16 to move rearward along the connecting threaded holes 114 and the sliding holes 115 of the pushing rods as a whole, thus pressing the pushing rods 165 against the top of the shaft 13 preventing the shaft 13 and the roller 12 fixed on it from movement upward and downward along the elongated slots 111 of the bracket 11. Therefore, skating and various performances of special arts can be carried out.

[0035] In the case of walking, the external force is applied to the pushing rod head 161 causing the rear connecting plate 162 and the connecting rods of the pushing rods 164 fixed on it to move foreward, as well as the front connecting plate 166 welded to the connecting rods of the pushing rods 164 and the pushing rods 165 welded to the front connecting plated 166 to move foreward horizontally along the sliding holes 115 of the pushing rods in the bracket 11. When the pushing rods 165 move foreward apart from the elongated slats 111 in the bracket 11, the roller 12 is pressed against the ground by the heel of the shoe causing the roller 12 and the shaft 13 connected to it received in the elongated slots 111 of the bracket 11 to move upward, as a result the roller 12 is retrieved into the recess 22 of the soles of the shoe body 2. Releasing the force applied to the pushing rod heal 161 accesses the springs 163 to move the pushing rod assembly 16 rearward along the connecting threaded holes 114 and the sliding holes 115 of the pushing rods as a whole, thus the pushing rods 165 are inserted underneath the shaft 13 preventing the roller 12 on the shaft 13 from movement upward and downward along the elongated slots 111 of the bracket 11.
